“Blindness separates us from things but deafness separates us from people.” – Helen Keller
The word Noise come from a latin word noxia meaning “injury” or “hurt” . Noise is an unwanted unpleasant annoying sound caused by vibration of the matter.
Vibrations impinge in to the ear drum of human or animal to setup a nervous disturbance, which we call sound. When the effect of sound a undesirable that it maybe termed as “Noise”.
When we are exposed to harmful noise – sounds that are too loud or loud sounds that last a long time – sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss. These sensitive structures, called hair cells, are small sensory cells that convert sound energy into electrical signals that travel to the brain. Once damaged, our hair cells cannot grow back. Noise-induced hearing loss is irreversible, and there is no cure.
Noise-induced hearing loss can be caused by a one-time exposure to an intense impulse sound, such as an explosion, or by continuous exposure to loud sounds over an extended period of time, such as noise generated in a mine or factory, or those who shoot regularly.
Sound is measured in units called decibels. On the decibel scale, an increase of 10 means that a sound is 10 times more intense, or powerful. To your ears, it sounds twice as loud. The humming of a refrigerator is 45 decibels, normal conversation is approximately 60 decibels, and the noise from heavy city traffic can reach 85 decibels. A noisy factory can reach levels of up to xx decibels.
Sources of noise that can cause noise-induced hearing loss include wind noise on motorcycles, firearms, mines, factories and construction sites, which can emit sounds from 85 decibels up to 150 decibels. Long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The louder the sounds, the shorter the time period before noise-induced hearing loss can occur. Sounds of less than 75 decibels, even after long exposure, are unlikely to cause hearing loss.
Hearing loss can be a direct result of an occupation, a recreational activity or simply exposure to loud sounds. From specialty custom earplugs to musicians’ sound attenuators, we offers a variety of protection and listening enhancement products.
Custom fit earplugs provide outstanding noise protection for a variety of recreational and occupational environments.
We provide hearing protectors fit snugly and comfortably into your ear-canal, allowing you to use telephones, walkie-talkies and earmuffs without having to remove them.

There are no proven ways to prevent cerumen impaction, but not inserting cotton-tipped swabs or other objects in the ear canal is strongly advised. If you are prone to repeated wax impaction or use hearing aids, consider seeing your doctor every 6 to 12 months for a checkup and routine preventive cleaning.
